  "purpose": "Re-derives a stated risk-report figure from a SUPPLIED source extract under a declared aggregation policy (filter set, netting rule, FX rate set, hierarchy roll-up). Returns the recomputed figure, a signed delta vs the reported figure, and a per-roll-up-node contribution breakdown so a break localises to one node instead of the whole report. HARD FENCE: every FX rate is supplied and asserted, never fetched (zero-egress); this recomputes the arithmetic over declared inputs and attests THAT, never an opinion on extract or reported-figure correctness, never a data-quality assessment (see art-481-rdarr-quality-scorecard), never a materiality judgement. First entry of the BCBS 239 / RDARR family, feeding the rdarr-attestation-cycle chain (art-481 + gate + attestation bundle). Not a data-quality scorecard or any general risk-data ingester. ECB Guide on effective risk data aggregation and risk reporting (3 May 2024) referenced as informative context only.",
